I could not believe the amount of information available for my Ford, which had a transmission problem. ALLDATAdiy.com showed me the information I needed to fix my problem. After relying on printed manuals in the past, which are more expensive than some people think, I find ALLDATAdiy.com provided me with all the information I needed for less money.- Pat
